<a href="http://inhabitat.com/tag/yarn-bombing/">Yarn bombing</a> -- the practice of knitting cozy, psychedelic sweaters and scarves for inanimate objects on the street -- grew to prominence in the middle of last decade, and it doesn't seem to be going away anytime soon. Leading the charge is <a href="http://www.magdasayeg.com/home.php">Magda Sayeg</a>, founder of <a href="http://inhabitat.com/knitta-please-graffiti-you-can-cuddle-up-to/">Knitta Please</a>, who has been called "the mother of yarn bombing". Sayeg has been producing some of the cleverest, most mind-boggling yarn art we've ever encountered.
